By the principle of conservation of angular momentum, the orbital period ratio of two orbits is proportional to the ratio of their radii raised to the power of three-halves. For a new orbit with a radius reduced to half of the original, the ratio becomes (R₂/R₁)³/²= 1/2√2. Therefore, the new orbitalRead more
By the principle of conservation of angular momentum, the orbital period ratio of two orbits is proportional to the ratio of their radii raised to the power of three-halves. For a new orbit with a radius reduced to half of the original, the ratio becomes (R₂/R₁)³/²= 1/2√2. Therefore, the new orbital period is 1/2√2 x T₁, where T₁ is the original period. If the initial period is 1 year, the new period becomes \1/2√2 years. This reduction indicates that the duration of the year will decrease significantly.
By conservation of angular momentum,
T₂/T₁ = (R₂/R₁)³/² = ((R₁/2)/R₁)³/² = 1/2√2
T₂ = 1/2√2 T₁ = 1/2√2 x 1 year = 1/2√2 year
Hence the duration of the year will become less.

In areas where farmers practice continuous cultivation without fallow periods, the soil nutrients become depleted over time. Continuous cropping without allowing the land to fallow prevents natural processes of nutrient restoration. The successive crops extract essential minerals from the soil, leading to nutrient imbalance and decreased fertility.
To address this, farmers resort to the addition of manure. Manure replenishes the soil by providing organic matter and essential nutrients, sustaining the soil’s fertility. Without fallow periods or nutrient-replenishing practices, continuous cultivation contributes to soil degradation, affecting crop yield and necessitating interventions to maintain soil health and productivity.

For a new orbit with a radius reduced to half of the original, the ratio becomes (R₂/R₁)³/²= 1/2√2. Therefore, the new orbital period is 1/2√2 x T₁, where T₁ is the original period. If the initial period is 1 year, the new period becomes \1/2√2 years. This reduction indicates that the duration of the year will decrease significantly.
By conservation of angular momentum,
See lessT₂/T₁ = (R₂/R₁)³/² = ((R₁/2)/R₁)³/² = 1/2√2
T₂ = 1/2√2 T₁ = 1/2√2 x 1 year = 1/2√2 year
Hence the duration of the year will become less.
